Abstract
A power converter is configured to increase bandwidth in response to a magnitude of the difference between the target output voltage and the actual output voltage. The converter includes a subtractor to receive a reference voltage and a scaled output as inputs, configured to produce an error as output, a functional block configured to receive the error as input and to produce a functional block output, a first multiplier configured to receive the functional block output and scale the functional block output by a first loop constant, and a second multiplier configured to receive the functional block output and scale the functional block output by a second loop constant. The functional block is configured to increase the error value fed to the first multiplier and the second multiplier by a factor f(x).
